Re: Cotidal Plot

Not aware of any slick way of drawing phase eg 330, 340,350, 0
with contour lines.

However, in color you could create a cyclic color map.
NCL has a crude one
   http://www.ncl.ucar.edu/Document/Graphics/ColorTables/cyclic.shtml
You could readily create your own color map.

then turn on color and use all the colors

   res@cnColorFill = True
   res@gsnSpreadColors = True

and turn off the drawing of lines and lin labels

   res@cnLinesOn = False
   res@cnLineLabelsOn = False

Good luck
